Command Mode
Interface Configuration (Wireless)
Command Usage
• The “min” keyword indicates minimum power.
• The longer the transmission distance, the higher the transmission power
required. But to support the maximum number of users in an area, you must
keep the power as low as possible. Power selection is not just a trade off
between coverage area and maximum supported clients. You also have to
ensure that high strength signals do not interfere with the operation of other
radio devices in your area.
Example
radio-mode
This command forces the operating mode for the 802.11g wireless interface.
Syntax
radio-mode <b | g | b+g>
• b - b-only mode: Both 802.11b and 802.11g clients can communicate with
the access point, but 802.11g clients can only transfer data at 802.11b
standard rates (up to 11 Mbps).
• g - g-only mode: Only 802.11g clients can communicate with the access
point (up to 54 Mbps).
• b+g - b & g mixed mode: Both 802.11b and 802.11g clients can
communicate with the access point (up to 54 Mbps).
Default Setting
b+g mode
Command Mode
Interface Configuration (Wireless - 802.11g)
Command Usage
• For Japan, only 13 channels are available when set to g or b+g modes.
When set to b mode, 14 channels are available.
• Both the 802.11g and 802.11b standards operate within the 2.4 GHz band.
If you are operating in g mode, any 802.11b devices in the service area will
contribute to the radio frequency noise and affect network performance.
